. 1 This invention relates generally to improveL mentsin al1-"adjustablekeeper or latching'device for" holding a window sash, which is hingedlyto the upper portion of a window fratrie,l man open position.-

The main objects of this invention are to provide an adjustable 'windowsash keeper device which is entirely automatic in-operation; to pro-'-vide'adevic'e of this character which mayv be readily and quickly-mounted on any hinged win-A dow sash and frame regardless of size; toprovide a'device of this character whereby a window sash which ishingedly secured to the upper portion ofthewindcw frame may be securedlyheld open atranydesired angle without manual manipulaa tion-oi thekeeper or latch; to provide a deviceofetliis character whereby a windowhinged at its upperlend may be held open by this device and then-quicklyclosed without requiring any hand manipulation of the latchi-ng means;to provide azdeviee of this character where the window sash canbelatched in an open position or closedby the-'same movement of thewindow sash; and to'provide-a device of this character which isrelatively simple in construction and inexpensive to manufacture.

An illustrative embodiment of this invention is'shown in theaccompanying drawings, in which:

Figure 1 is a front view of our invention shown secured to a windowframe and sash, the frame and sash being shown broken away.

showing the window sash in dotted outline, in*

various raised positions and illustrating in dotted outline, the motionof the device of our invention.

1 In the drawings we disclose generally a window sash I, having a paneof glass 2 secured therein inthe usual manner, the sash being pivotallyor swingably secured by hinges 3 within the side and" upper frames 4 and4', respectively, in theV conventional manner. As is clearly illustratedFig-1 of the drawings, the upper leaf ofthe hinge 3 is rigidly securedto the top frame 4 by screws' 5, or the like, while the lower leafthereof is rigidly secured to the top bar I of the window sash l byscrews 1, or the like. This is the usual type of window sash and framefound in basements. y

lhedevice of our invention comprises an L- shaped arm, preferablyconstructed of metal, the

long leg 8 of which is provided with spaced apertures 9 and I0 toreceive the wood screws I3 for rigidly securing the arm to the' side barI" offthe I'. The short legi I extends at right 'angles 2 to the legBand is provided with an aperture |25 lll-normally vertically disposedswingingr` link :2.1'1411'32` has'an aperture 33 adjacent the uplp'erend thereof whichisadapted'toreceive a headed bolt A34, which threadedthrough the aperture 33 and the aperture I2' 0f 'the leg I'I whereby topivotal-111, secure the arm 32 to the leg Il. The bolt"34fis providedwith a nut 35 and a washer 36 positioned one on each side of the arm 32to secure the arm 32 to the leg II and provide a bearing thereforrespectively. A horizontally. disposed bearing rod or pin 31l isintegrally se cured adjacent the lower endof the arm 32' in anysuitablemanner such as by welding, riveting or the like.l The pin 31 extendslaterally and'at right angles to the link arm 32.

A horizontally disposed elongated U-shaped bracket I4 (see Figs. 3, 6and 7) also preferably constructed of metalis provided with a pair offeet I5 and I6 at the open end thereof, each disposed at right angles tothe bracket I4. Each foot I5 and I6 is provided with an aperture throughwhich wood screws I8 and I9 respectively are threaded to rigidly securethe bracket I4 to thel side wndow frame 4".

An' adjustable sliding metalblock 20 is adapted to nt loosely betweenthe arms I4" and I4 which formsa guideway or slideway I1 therefor.blockZU is securely held within the slot I1 by a guide bar 2|, which issubstantially equal to theI Width of the bracket I4, and which ispositioned on the right-hand side of the bracket I4. A'

plate22, slide block 20, and guide bar 2I respectively, whereby saidblock '20 is slidably se` cured "within the. slideway I1. A pin or rivet23 threaded'throughsuitable aligned apertures 3il'v and 3l 'contained-lnthe latch plate 22 and 'slider block: 2u respectively, holds thel latchplate' 22" rigidly in a vertical positionv asA shown especiallyv Theteeth 23` in Figs. 3 and 4 of the drawings; onthe latch 22 are'upwardly'directed anddiagonally` disposed on the forward'edge of the latchvplate 22' whereby to forma plurality of notches 23.1A Whichfacei'fhesash" I. The top and bottom of thelatch 22 are each 4provided withdiagonally' disposed lrounded ends or cam-likev surfaces 22.! and :2;2respectively.

Tile' pin 31 of 'the arm 32 is aligned with' .theA latch plate 22 and isadapted to seat in the notches" InV operationth'elatch plate-22 is"slid' into the deslredposit'lon on the bracket I4 by adjust ingthesliding' block'rZU and'v securingit to thek bracket I4 by vtighteningthe nut 2501iv` the bolt 24. THe-window sash I is then-raised inwardly:

The"

Y A headed bolt 24 having a nut 25'; thereon is threaded throughsuitable aligned apertures 26, 21 and`28 contained inthe latch' Byfurther movement of the sash (to-jv that shown in dotted lines in Fig.6) I the rod will automatically move upwardly'on vthe cam-like surface22.2 and along the inner face edge of the latch plate 22 and seat itselfin a notch 23.I and hold the sash in the position selected.

It will be apparent from examining Figs. 6 and 7 of the drawings that asthe sash I is further raised at any time the pin 31 will alsoautomatically slide out of the notches 23.I until said pin passes overthe cam-like surface 22.I (see dotted line disclosure in Fig. 7) andvswings behind (or to the right as shown in Figs. 6 and 7) the latchplate 22, whereby tc'becom'e disengaged fromthe latch plate 22 andallowing the sash I to vbe closed against the window frame. It will beclear that as the notches 23.I are upwardly inclined the pin 31 iseasily disengaged therefrom by merely lifting the sash I upwardly. y

It will also be apparent that the point at which the latch plate22 issecured to the bracket I4 will depend entirely on the length of the linkarm 32. If, as shown in the drawings, the link arm 32 is substantiallyequal to the over-all length of the latch plate 22 then the latch plate22 will be anchored to a point substantially in the center of thebracket I 4, However, if the link arm 32 is shorter than the latch plate22, the latch plate 22 will be anchored closer to the to andv adjacentone edge of the window sash, bracket adapted to be secured yat one endto the window frame immediately adjacent said link arm and below thehinged upper end thereof to projectoutwardly from said window framesubstantially perpendicularly thereto, a latch plate, means vadjustablysecuring said latch plate on said bracket at dierent distances from theplane of said window frame, said latch plate having downwardly inclinednotches therein opening out of an upright edge of said latch platefacing the window sash, said latch plate being disposed transversely onsaid bracket and parallel to the plane thereof, and a stud on the freeend of .said link arm disposed at right angles thereto and substantiallyparallel to the hinge axis of the link arm adapted for cooperativeengagement with the notches on said latch bar.

3. A latch device for holding a window sash in open position and whereinthe window sash is hingedly secured at its upper end to and within isaid frame comprising an arm adapted to be sesash I and if the link armis longer than the latch 'f plate 22, the latch plate 22 will beanchored farther away from the sash i. It will be equally clear theneven though one link arm 32 is used the latch may be secured in variouspositions to which the window may be maintained in open position.

, It is to be understood that numerous details may be altered or omittedwithout departing from the spirit of this invention, as dened by thefollowing claims:
